CASH REGISTER.

Application filed. May 8, 1925, Serial No. 28,959, and in Germany June 16, 1924.

This invention relates to cash registers having differentially movable members influenced by keys and in which the depression of a key of a row of keys causes a determined positioning of the corresponding differentially movable member. Devices of this character are made use of for instance when the keys of one row are designed to select transactions, while the keys of the other row are sellers keys.

According to the invention two of the differentially actuated members of two keyrows arranged side-by .side are in connection with each other in such a manner that the differential movement of the one member can be stopped through the medium of the other one.

With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements'of which are set forth in appended claims, and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of the specification.

In these drawings the subject-matter of the invention is illustrated as applied to a cash register having a plurality of totalizers arranged in a drum.

Fig. 10 is a plan view of two differentially movable members, partly in section,

Fig. 11 is a front elevation of these members, partly in section.

Mounted on the casing partitions A are four rows of amount keys 13, Figs. 1 and 2, and two rows of special keys C, Figs. 1 and 4, namely a row of sellers keys I to V and a row of line of transaction keys A, G, R. The amount keys B cooperate with feelers o Fig. 2, of coupling bolts pivoted to differential members B the sellers keys cooperate with a feeler 0 Figs. 10 and 11, of a coupling bolt 0 pivoted to a differential member C and the keys A, C, R cooperate with a feeler 0 Figs. 4:, 5, 10 and 11, of a coupling bolt 0 pivoted to a differential member C The differential members B Fig. 2, which are freely rotatable on a shaft B are actuated by means of driving members formed by engaging disks 5 rigid to the said shaft and to which a crank gear imparts an oscillating movement at each operation of the machine. The crank gear comprises a crank 2)", Figs. 1 and 6, fast to the shaft B and connected by a rocking rod 03 with a crank d carried a short shaft D. The shaft D which is mounted in the casing A is connected with the driving shaft D by, pinions d d and executes a revolution at each operation of the cash register. When the engaging disk Zfimoves upwardly its shoulder b (Fig. 2) engages the coupling bolt 5 and carries the differential member B along with it until, by the feeler striking against the foot of the depressed key- B, the coupling bolt b is brought out of engagement with the shoulder?) of the disk 6 and into engagement with a series of teeth a of the key bank whereby the differential member 13 is locked.

During the downward movement of the engaging disk I) a pin 6 carried by the same strikes against the differential member B and returns it into zero-position.

The pinion d meshes with a pinion e of the same size, Figs. 1 and 6,,fixed to a shaft E which carries a disk E provided with a cam groove e Figs. 4 and 5. As the pinion d executes a revolution at each operatlon of the machine as mentioned above, the disk E has likewise imparted to it a revolution at each operation of the machine. groove e is engaged by a roller 0 carried by a pitman C. The pitman C is guided by The cam.

its fork-shaped end on the shaft E and pivoted by its other end to a rocking lever U which is mounted on a shaft The free end of the lever C is in pivotal connection with a link C pivotally connected by a pin 0 with one of the two engaging disks c for the differential members C and 0 which being of such a shape that, during the downward movement of the disks If appropriate to the amount keys, there will take place the full oscillatory movement (downward and upward) of the special key engaging disks 0 so that the last-said oscillatory movement will be terminated prior to the beginnin of the adding movement of the amount di erential members B which takes place during the upward swinging movement. During the upward swinging movement of the en aging disks 0 their shoulders 0 engage t e coupling bolts 0 and carry along with them the two differential members C and C until their feelers 0 strike against the feet of the depressed special keys. During the downward movement of the disks 0 pins 0 carried by them strike against the differential members C and U and return the latter to zero position. If none of the special keys A, C, R is depressed, the appropriate feeler c is stopped and the respective differential member C uncoupled and locked by other means. The pivot pins 0", Figs. 4, 5, 11, of the feelers c of the differential members C and C" are provided with extensions (stop pins 0" and a, Fig. 11) which ass through a slot ,at, Figs. 4 and 10, of t e corres onding common casing wall A as well as through slots 0 of the key locking rockers c. The two in extensions 0", 0 overlap each other by flattened portions, Figs. 10 and 11, in such a manner that upon the feeler 0 of the differential member C being stopped the feeler of the differential member C is likewise stopped, while the feeler of the differential member C" isallowed to move independently of the differential member C in the direction of its difl'erential motion. Therefore, if none of the keys A, C, R but only one of the keys I to V is depressed, the differential member C will move unhinderedly past the keys A, C, R and continue its movement until the differential member U is disenaged from the engaging disk 0 and locked y' its feeler striking against the depressed s ecial key (I to V). When this takes place t e'stop pin 0" stops the feeler of the differential member C by means of the stop pin 0 so that the member 0 is likewise uncoupled and locked and both differential members C and C are brought into the same position, which corresponds to the depressed key of the row of keys I to V.

As will be described hereinafter, the positioning of the differential member C causes one of eight auxiliary totalizers to be brought into cooperative engagement, five of these totalizers being designed to register the cash sales of the several sellers (sellers totalizers I to V). The selection of one of these sellers total zers by means of the differential member C is controlled by depressing one of the keys I to V. In this case it is necessary that none of the keys-A, C, R is depressed. The differential member C is in this case arrested by the feeler 0 of the difierential member C through the intermediary of the pin extensions 0", 0 The three other totalizers serve to register in common special transactions of all sellers (expenses, credit, bills). In such cases there is depressed besides the sellers key (I to V) the respective special key (A. C, R) and the selecting of the special totalizer is effected by positioning the differential member C the appropriatefeeler striking against the depressed special key (A, C, R).

The described arrangement has for its object to cause the differential member (7 which is connected alone with the selecting device for the sellers totalizing I to V and transaction totalizers A, C, R, to be positioned always so as to actuate one of these totalizers no matter which keys may have been depressed. As long as cash sales are registered, with which none of the keys A, C, R is depressed, the amounts are accumulated in the individual totalizers allotted to the individual sellers (I to V). In case, however, one of the transactions A, C, R is recorded by a seller, the amount in consideration is not transmitted to the respective sellers totalizer but to the totalizer corresponding to that transaction.

Arranged to mesh with a toothed portion 6 Fig. 2, of each difl'erential member B is a pinion b, Fig. 1, rotatable on a shaft 6 and adapted to be coupled by means of a swingingly arranged pinion]; with a p nion b Figs. 1 and 2, likewise mounted tor rotation on the shaft b and of the same size as'pinion b. Each pinion b is in mesh with a pinion P. The pinions f are fastened to the ends of nested hollow shatts F which surround a shaft G mounted in the casing A and extend into the drum G r gidly connected to the shaft G. In the nterior of the drum G a toothed adding disk 1 is fixed to the end of each hollow shatt F. The totalizers k arranged in the ira-me H are adapted to be thrown into engagement with the adding disks f. The totalizer carriers H are mounted for rocking motion in llU iau

the head walls g of the drumG by means of pins k Fig. 3. mounted on it a roller h. By the cooperation of the rollers k with the arran ement hereinafter described, the frames H ave imparted to them the rocking motion necessary for throwing the totalizers into or out of cooperative engagemnt.

The toothed portion 0 of the differential member C of the row of keys A, C, R meshes with an intermediate pinion i, Fig. 1, mounted for rotation on the shaft 6 9, Fig. 4, and meshing with a pinion 71 This pinion a" is fixed to one end of a hollow shaft 1? surrounding the outermost one of the nested "hollow shafts F and the other end of which see particularly Figs. 7 and 8. The block totalizer carrier H rocked about the axis of J 4 is provided with an arc-shaped groove i traversing it. When the block Jis in its outermost radial position, Fig. 7 ,an annular groove 2' concentrical to the axis of thehollow shaft i and extending up to the two sides of the block J, is completed by the groove 11 into a closed ring which traverses the block J*. This annular groove is engaged by the adjusting pins (rollers 72?) of the totalizer carriers H so that by rotating the disk J the block J 4 is either adjusted to register with the roller h of one of the totalizer carriers or with the idle place, Fig. 7. The shifting of the block J takes place by means of the section of a curved groove is, 70 provided on the disk K andengaged by a roller 71 carried by the block J. The section is of the groove 70', is lies concentrically with relation to the axis of the hollow shaft 70 As long-as the roller i of the block J 4 is in engagement with' the groove section is, the block J remains in its innermost osition. During this'time the totalizer w ich has itsadjusting roller h in engagement with the groove i of the block, is coupled with the adding disks 7. If during the rotation of the disk K the roller 5 enters the section is of the groove In, In, the block J 4 is shifted radially and the the ins k T e operation of the described arrangement is as follows:

By depressing amount keys B the adjustment of the respective adding disks f and by depressing one of the special keys C the adjustment of the appropnate totahzer h is -Each frame H has.

from the tenth to the nint prepared. When the machine is operated the amount diiferential members B are first restored by the engaging disks 5 from the position they assumed from the previous operation into zero position. During this stage the coupling pinions b are rocked out of action so that the adding disks 7 are not in connection with the differential members B The differential members B are then carried upwards by the engaging disks 1) until stopped by the depressed keysf The addin movement thus limited of the diiferentia members 13 is transmitted to the adding disks f which are positively connected with the members B after the coupling pinions 6 have been thrown in, and tothe totalizer h which is in engagement with the addingdisks f.

If none of the special keys I to V and A, C, R for one of the totalizers is depressed, the two differential members C and C however, are moved by the engaging disks 0 up to the uppermost position which in the machine shown is the tenth place, Fig. 4. For the rest, the mode of operation of the engaging disks 0 and of the differential members C and (1 is the same as that of the engaging disks 5 and-differential members B of the amount difi'e'rential mechanism. However, owing to the driving action of the grooved disks E the positioning takes place so much quicker that the full oscillatory movementof the engaging" disks (upward and downward) is already terminated when the disks 6 and the differential members B have reached the zero-position (below). During the downard movement I of the engaging disk 0 the curved groove kf of the grooved disk-K positively connected to the disks, causes the sliding block J to be moved outwardly fromthe inner position it assumed from the previous operation of the machine; thus the roller k of a totalizer carrier H that happens to be in engagement with the groove '5 of block J is moved back into the path of the annular groove i of the slotted disk J and the appropriate totalizer is placed out of engagement with the adding disks 7. If the block J was adjusted to the idle place, the said reversal of the block takes lace during a rotation of the disk K which corresponds to the return movement of the differential member G and of the engaging disk 0 place and if the block J was adjusted to one of the rollers h the reversal is accordingly efi'ected beforethe summit of the groove section is coincides with the radial middle line of the block J. When vall of the rollers h" of the totalizer carriers H lie in the path of the annular groove 23 of the disk J, there may take place the return rotation of the disk J whlch is efiected" by the pin o im- I pinging on the differential member C positively connected to the disk J. After the differential member C and the engaging disk 0 have been restored into the lowermost position, Fig. 5, the disk 0 is again raised by the reversal of the crank drive, the coupling bolt 0 of the differential member 0 being carried along by the shoulder 0 of disk 0 up to the key'stop and thereby disengaged from the engaging disk 0 and locked. This adjustment of the differential member C and of the slotted disk J positively connected with the member -C causes the sliding block J to be adjusted to the totalizer carrier H corresponding to the depressed special key, whereupon the cam groove disk K the rotation of which is continued up to the tenth place, shifts the sliding block J inwardly through the inter mediary of the curved groove section 70 and of the roller 2" and causes the selected totalizer h to be thrown into engagement with the teeth of the adding disks f Now, by coupling the pinions b, 6 positive connection is then established between the amount differential members B which have in the meantime been moved down. and the appropriate adding disks f whereupon these differential members are positioned by the upward movement of the engaging disks The adding movements imparted to the differential members B are thereby transmitted by the adding disks f to the totalizer k which has been moved into cooperative engagement. Upon the adding movement having been terminated the pinions b, b are uncoupled.
